Application tiled November 22, 1917. Serial No. 203,420.

1 represents the keel, 2 a keelson bolted to the keel by the long bolts 3 and d, and 5 a longitudinalpartition or bulkhead forming i a sort of continuation of the heel and keelson to supply longitudinal strength and stidness to the vessel, while at the saine time, forming an inner wall or partition for said tanks, as will appear more fully hereinafter.

Y 6 represents vertical stanchions or posts on each side of the bulkhead 5,- the function of Whiehwis to support and stillen said bulkhead, and they are secured Yat their lower ends to the latter, and tothe heelson as by the through bolts 7, while they are secured at their upper ends to the longitudinal beani S, or upper edo'e of said bulkhead 5, as by the through bolts 9. The transverse frames 10, are each made of a pair of sets of timbers 1l and 12, as shown, breaking joints with each other, as at 13, Vand 14: respectively. Said transverse frames are continuous from side to side, and pass between the keel 1 and keelson 2, as best shown'in Figs. 3 and ,Immediately above the Jframes on each side 0l' the keelson 2 are the longitudnals 15 which are securely'bolted to said keelson 2, by the through bolts 16, and on each side of the keel 1 are corresponding longitudinale 17 which are likewise bolted to the keel 1, b v bolts similar to those lettered 1G, but not` appearing in the drawings.

f vThe said longitudinals 15 and 1'?y are securely bolted to each other and to the transverse Jframes l() by the vertically disposed through bolts v19, so that the keel and keelson 90 as well as the frames are bound together in the most solid manner. lnv order to still further stillen the structure, a plurality of outer longitudinal strakes or timbers l20, heavier than the v normal,l are successively placed on each side of the outer timbers 17, and are further secured to the transverse frames 10 as by the through bolts 21, thus still further bracing the joint between the transverse frames and the keel and lteelson. 100

The main frame-like structure of the vessel consisting of said transverses 10, keel and lreelson, and longitudinal bulkhead 5, being thus firmly and strongly united into a single structure,'there is next provided on los the inside of this structure the wooden tanks forv carrying the oil or other liquid cargo, and they are so built into the said structure as to still further brace the ship as a whole,

and te les@ langtleel and .transverse 1.10

strength,`as will now be disclosed. On the interior of the vessel at or near the bilges thereof are placed the longitudinal timbers 25 constituting the lower outboard corners ot'V the tanks, and above these said timbers 25, and extending to the upper longitudinal timbers 26, are the outboard walls of the tanks. Said walls 27 are securely braced by the vertically disposed stanchion-like members 28, placed on the inside of the tanks as shown, and said walls 27 are further braced by the similarly disposed vertical stanchion-like members 29 placed on the outside of said tanks as best shown in Figs. 3 and V6. In order to firmly support the said vertically disposed members 29, and thus to more etfectually take the strain exerted on the interior of the tanks 30, there is provided the horizontally disposed short transverse members 31 and 32 extending from the walls 27 of said tanks to the outer transverse frames 10, as clearly shown in Figs. 3 and 6.

. There is also provided above each set of members 31 and 32 the longitudinally disposed members 33 and 34 which contact with said members 29, and said members 31 and 32, as illustrated. The said members 33 are firmly' bolted to the members 31 as by the through bolts 36, and the vsaid members 34 and 35, which are placed respectively above and below the members 32, are firmly bolted to said members 32 as by the through bolts 37. I

In order to still further take the outward thrust exerted on tlie walls 27, there is provided the additional longitudinal members f 38 and 39 which are rmly bolted to said members 32, as. shown, and between said members 33 and 39, and the transverse frames 10, there is provided the additional longitudinal members 40 and 41 which are likewise firmly bolted to the members 32 by the through bolts 42, as will be clear from Fig. 3 of the drawings.

At or near the tops of the stanchion-like members 29 there is provided the successive longitudinal members 43, 44, 45, 4G, 47 and 48, and above the transverse beams 49 there is provided the complementary longitudinal members 50 and 51. The said members 43 are securely bolted to and through the beams 49. as by the bolts 52, the said members 5() above said beams and the said members 44 and 45 below said beams are firmly bolted together by similar through bolts 53, and the said members 51 above the beams 49 are securely bolted to the said members 46, 47 and 48 as by the through bolts 54.

At or near the bottom ends of said vertif cal stanchions 29 I place the longitudinal filling members 56 and bolt the same securely to said members 29 as by the through bolts 57. It thus results that the outward thrust, experienced by the tank walls 27. is resisted by the solidly and firmly braced construction shown, so that there is no possible way for the said walls to spring and thereupon permit of leakage of the oil therethrough.

In order to still further stiften the structure, on the interior ofthe tanks 30 there is provided the longitudinally disposed transverse members 60 which are preferably located in line with the members 32, and which, with said members 32, constitute horizontally disposed bracing members from one vertical frame 10 on one side of the vessel 'to a corresponding vertical frame 10 on the opposite side of the vessel. It therefore results that the two setsof bracing members 60, when combined with the corresponding two sets of bracing members 32, constitute a sort of secondary transverse beams located below the beams 49, which serve to effectually stiii'en the ship at or about the middle of the depth of the tanks 30.

It will now be seen that when one considers the firm manner in which the keel, the keelson, bulkhead 5, and the transverse frames 10 are secured together, and when one considers the upper transverse beams 49 extending from side to side ot the ship, and the secondary or lower transverse beams or bracing members 32 and 60 which extend from side to side of the ship, there is provided an exceedingly strong vframe or structure which. is still further stiti'ened by the two longitudinally disposed walls 27 of the tanks 30, and by the bracing members 29, 28, 100 31 and 33` which support said walls 27.

This said structure is still further enhanced by carryingv the walls 27 continuously throughout the length of the tanks on each side of the center line bulkhead 5. It 10' -thus results that the structure just described really provides three longitudinal bulkheads. one passing through the center ot the vessel, and constituting au extension of th(` keelson, while the other two are located near the outboard portions of the vessel, and all three being rmly built in and furnishing a portion of the longitudinal strength of the vessel. The three longitudinal bulkheads lettered 5 and 27 are divided ott' at suitable 115 intervals by the transverse partitions 70 to form the ends of the tanks 30, and said ends 70 are provided on one side with the vertically disposed stancliion-like members 71, in order to more eii'ectually brace the same.

Said ends 70 and members 71 are conveniently stepped on the transverse members 72 resting below the lower ends ot' the members 71, and the ends or partitions 7() of the tanks to provide a better and more liquid tight joint- Opposite the vertical members 28 located in the tour corners of a tank such as 30, there are located in the corners of similar tanks. duplicate members 23. so that at a point such as 7 5, (see Fig. 6), where four 130 the quarters of the crew, 110 a smoke stack and lll any suitable masts which it is desired to provide.

It will now be clear that by firmly uniting the keelson and keel to the fra-mes 10 by means of the long through-bolts, or tie rods 3 and 4, by providing the longitudinal inner stiiilening members '15 on each side of the keelson, and the longitudinal outer stiifening members 2 0 on each Side of the keel and by firmly binding said members l5 to said members 20 and to the frames l0, an exceedingly strong joint is had between said frames and said keel and keelson, which is enhanced by the through bolts or tie rods 16 and .21. It will be further observed that the upper outboard longitudinal stiffening members 43, 45, 48, 50 and 51 are similarly tiedto the beams 49 by the tie rods such as 53 and 54, and to the frames l0 by the tie rods such as 44 and 94 so that the outer rim of the hull is rendered exceedingly stiff, or rigid, thus producing a skeleton frame work out ofwood capable of resisting great strains. And it will now be clear that this said strong skeleton frame work isV very greatly stilened longitudinally by the three parallel bulkheads 5 and 27 which are transversely braced by the beams 49, 32 and 60, as well as by the end transverse bulkheads 7100, extending from side to side of the vessel.

In other words, there is built into the skeleton frame work above described a rectangular frame work formed by the bulkheads 27 and 100, and through the center of which passes the bulkhead 5. This said rectangular frame work is further braced transversely by the tank wall partitions 70, and the beam members 32 and 60 and their associated members 28, 29, 34, 38, 40, etc.

In addition to the foregoing the transverse steel bulkheads 96 extending from side to side of the vessel at each end, still further stiiien the above mentioned skeleton frame work, and enable the vessel to etfectually resist twisting and racking strains, which otherwise might open her seams. In order that the through bolts or tie rods such as 80, for example, may fit liquid tight, the holes which they fill are bored slightly smaller than said rods, and the latter are driven in place, all as will be readily understood from Fig, 4. Again by applying the flexible sheet material 83, 84 between the outer skin 85 and the frames, a water tight outer sheathing is readily produced.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention and therefore, I do not wish to be limited to the above disclosure except as may be required by the claims.
